20. **SAFE AND ABANDONED BABIES ACT**
Where are safe havens?
In Illinois, the safe havens for newborns are:
Staffed fire stations
Staffed police stations
Hospitals
Emergency care facilities
What does the law do?
The law is intended to provide an alternative to the parents of newborn infants to relinquish their unharmed infants to staff in safe havens while remaining anonymous and avoiding civil or criminal liability. It is recognized that establishing a traditional adoption plan through a private or public adoption agency or choosing to parent the child is a preferable parenting plan to abandonment or relinquishment of an infant. However, the purpose of this law is to reduce the risk of harm to a newborn by a parent who may be under undue stress.
